INVALID-BED.

Application filed. June 28,1913.

To all whom it may concern:

Be it known that I, J OI-IN R. PHILLIPS, a citizen of the United States, residing at city of Poughkeepsie, in the county of Dutchess and State of New York, have invented cerj tain new and useful Improvements in Invalid-Beds, of which the followmg 1s a specification.

This invention comprehends certain new and useful improvements in adjustable beds for invalids, and it has for its primary object to provide a simple and efficient device of this character embodying improved means whereby the bed bottom or frame proper may be easily and quickly adjusted to assume different angular positions, as required A further object of the invention is to provide an improved invalid bed in which the bed frame designed to directly support the patient, may be inclined not only longitudinally, but laterally, with eitherside raised above the other so as to facilitate the changing of the bed linen and for other purposes, built so that the air may freely circulate to all parts thereof so as to prevent bed sores and make the patient comfortable in warm weather; to provide an improved construction and arrangement of parts for elevatingdifferent portions of the bed frame so as to change the position of the patient and with out subjecting him or her to any strain or inconvenience; to provide an improved construction of hinge members whereby the bed frame may be tilted laterally as a whole in one direction or the other and having its sections lockedor latched in rigid relation to each other; and provide, instead of the ordinary wire springs, a canvas tape lacing threaded through eyes secured to the bed frame on the inner edge thereof.

A still further object of the invention is to provide an mvalid bed whlch lncludes a bed bottom or frame structure in three SEC-l tions, the intermediate or middle section having a removable seat formed with a plurality of relatively small apertures and a larger opening for purposes hereinafter fully set forth. And the invention also aims to generally improve devices of this character so as to render them more comfortable to thepatient and more useful and generally commercially desirable.

.lVith these and other objects in view, as

will more fully appear as the description Specification of Letters Patent.

Patented A11 25, 1914. Serial No. 776,306.

proceeds,the invention consists in certain constructions, arrangements and proportions of the parts that I shall hereinafter full-y describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in

which Figure 1 is a side elevation of an invalid bed constructed in accordance with my invention, the bed frame being shown in dotted lines in diflerent positions. Fig. 2 I is a top plan View of the bed, a mattress being indicated as applied to the bed frame. 5 Fig. 3 is a horizontal sectional view, the section being taken approximately on the line 33 of Fig. 1. Fig. 4 is an end view, the bed frame being shown in dotted lines in a laterally tilted position. Fig. 5 (Sheet 1) is a fragmentary perspective view of one corner of the device. Fig. 6 is asimilar view of one of the eyes and tape connected thereto. Fig. 7 (Sheet 2) is a detail plan view of lone of the hinge connections between the ,head and middle sections of the bed frame j and illustrating, the specific means for supportingsaid frame intermediate of its ends whereby it may tilt laterally. Fig. 8 is a detail; sectional view on the line 88 of Fig. 7. Fig. 9 is a fragmentary section taken on the line 99 of Fig. 3.

Corresponding and like parts are referred to in the following description and designated in the accompanying drawings by i like reference characters.

The supporting framework of my improved invalid bed comprises head posts 1 and footposts 2 connected together intermediate of their ends by means of longitudinal brace bars 3 connected in the detachable manner illustrated in Fig. 5, to corner castings i. The head posts 1 are connected together by means of transverse braces 5 integrally or otherwise secured to the corner castings l, and the foot posts 2 are also connected" together in .a similar .;manner. The corner posts 1 and 2 are pro vided at their upper ends with socket memibers to which longitudinal braces 7 and itransverse braces 8 are secured, as clearly iillustrated in Figs. 1, 2 and 4. Preferably, the entire supporting framework is formed of tubular metal whereby strength is combined with lightness and the supporting frame- .work is-preferably mounted upon casters or are corresponding brackets 11. A trans-.

verse shaft 12 is journaled in bearings formed in the brackets 10 and a corresponding shaft 13 is journaled in bearings formed in the brackets 11. Preferably both of these shafts are squared or otherwise formed at both ends to accommodate a detachable crank handle 18. A pair of winding drums 1 1 are secured to each of the shafts and straps or cables 12 are adapted to wind upon one pair of drums, said straps passing upwardly from pulleys 19 secured to the ends of a transverse shaft 20 journaled in bearings 21 secured to or formed on the upper longitudinal braces 7, theends of the straps being secured to eyes 23 that are fastened to the head section 28 of the bed frame 22. Similar straps 13 are adapted to wind over the other pair of drums and these pass upwardly over pulleys secured to the shaft 20 like the pulleys 19, the last named straps thence passing horizontally toward the foot portions of the framework and finally passing down over pulleys 2 1 secured to a transverse shaft 25 which is j ournaled in bearings 26 on the upper longitudinal braces 7, the ends of the straps 13 being secured to eyes 27 fastened to the foot sections 30 on the bed frame 22. Each of the shafts 12 and 18 is provided with a ratchet wheel 15 engageable by pawls 16 carried by the brackets or supporting members 10 and 11, whereby the shafts may I be held fixed after the parts have been properly adjusted. It will thus be understood that the shafts 12 and 18 are independently movable, whereby the bed frame may be adjusted to different longitudinally inclined positions and the head portion and foot portions adjusted to various angles, one independently of the other. The bed proper or bed frame 22 is also preferably composed of tubular metal and comprises the head section 28 and foot section 80, hereinbefore referred to, and an intermediate or middle section 29. The side bars of the head section 28-are jointed or horizontally connected to the sides of the middle section 29, as best seen at 31 in Fig. 7, and the sides of the foot y H section 30 are correspondingly connected to 55 the sides of the middle section 29. In order to hold the head and middle sections rigidly in alinemen't with each other, when desired, 1 provide the laterally swinging latches 32 which are pivotally connected to the sides of the middle section 29, as at 33 and are adapted to swing underneath angular keepers 3i secured to the sides of the head section 28 at the adjoining ends thereof. When not in use, the latches 32 may be easily swung around so as to lie over andupon the sides of the middle section where they willbe entirely out of the way.

The pivot or pintle 35 of each of the joints 31 which connect the middle section to the head section, is extended laterally in an outward direction to form a shank or stem 36 formed at its extremity with a rounded head 37 adapted to rest in a socket formed on the upper surface of the inwardly projecting flange of a collar 38 clamped upon and secured to the adjoining longitudinal brace 8. By this construction and arrangement of the parts, the joints mav turn in any desired direction while at the same time they are capableof being raised entirely free of the bearings, The middle section 28 is provided close to the adjoining portions of the foot section 30 with t t-shaped clips adapted'for a freely rotatable engagement with corresponding clips 39 secured to the longitudinal braces 3 and the sides of the foot section 30 near the opposite ends thereof, are provided with corresponding clips 10 designed for engagement with clips 4-1, as best illustrated in Figs. 3 and 5, it being understood in this connection that the clips 11 are formed on their rear edges with upstanding lugs 42 to prevent any accidental detachment of the parts by longitudinal movement. By means of these clips and the detachable bearing supports comprised by the laterally extending pintles35 and the collars 38, the bed frame 22 may be supported solidly in a horizontal position without any strain at all upon the straps 12 and 18, and besides, the bed frame as a whole, or the different sections thereof, may not only be inclined as required, in a longitudinal direction, but the entire bed frame may be tilted laterally as best illustrated in dotted lines in Fig. 4. This last named movement or position of the bed frame may be found particularly desirable when it is desired to change the bed linen, for the frame may be lifted first to one side and the sheet spread on the bed with the patient at the then lowermost side of the latter and the sheet is then slipped underneath, the'bed frame lowered and the other side raised to a corresponding position and the sheet finally pulled underneath the pabeing preferably provided with threaded shanks 4C5 screwed into the side of the bed frame at the inner edges thereof. This construction constitutes an advantageous feature in that the tapes can be easily removed and washed and kept in a sanitary condition. y

As best illustrated in Figs; 3 and, 9, the

middle section 29 of the bed frame maybe provided with a board 16 designed to form a seat for the patient when the head section is inclined upwardly andthe foot section downwardly, said board being provided at its side edges with binding strips or cleats 27 formed with outstanding flanges whereby the board may be raised in a detachable manner upon the inwardly extending flanges or lugs 48 riveted or otherwise secured to the side bars of the middle section. The seat 46 is formed with a plurality of relatively small apertures 49 for air circulation and with a relatively large opening 50 which may be used by the patient when unable to leave the bed. For a fractured leg and to eliminate the use of splints, I provide small pulleys 51 mounted on the shaft 25 so that tapes may be fastened to the broken member and run over the pulleys and have weights attached thereto to produce the required extension.

From the foregoing description in connection with the accompanying drawings, the operation of my improved invalid bed will be apparent. In the practical use of the device when it is desired to support the bed frame 22 in a horizontal position, the straps 12 and '13 are sufficiently relaxed so as to permit the bed frame to be solidly supported by the collars 38 underneath the heads 37 of the pintles 35 and by the clips 39 on which rest corresponding clips and the clips 41 on which rest the clips 40. Thus, all strain is taken off of the straps 1'2 and 13. Whenever it is desired to incline the bed frame as a whole in a longitudinal direction, or the head section at a varying angle to the foot section, the shafts 12 and 13 are manipulated in an evident manner and held fixed by means of the ratchet and pawl connections with the bed frame in the desired adjusted position. Furthermore, either side of the bed may be raised above the other so as to laterally incline the bed frame whenever required and when it is desired to hold the sections in any longitudinal alinement and in rigid relation to each other, it is only necessary to swing the latches 32 underneath the keepers 84.

While the accompanying drawings illustrate what i believe to be the preferred embodiment of my invention, it is to be understood that "the invention is not limited thereto, but that various changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of the invention as defined in the appended claims.
